Answer=176ft^2
Area of a square is l x w or 16 x 14=224
Area of a triangle uses the formula ab/2, so it would be 16 x 6/2=48
224-48=176
Answer:
b is 15 less thsn the product since it subtracts 15 from 7n
Answer:
the answer is 29.1
Step-by-step explanation:
do 30 * .97
Answer:
1.2
Step-by-step explanation:
Given that X is Normally distributed random variable with an unknown mean μ and known standard deviation 6
Hence we can say for a sample of size 100, the sample mean will have a std deviation of =
Since population std deviation is known we can use Z critical value for finding out the confidence interval
For 95% using (68-95-99.7 rules) we have z critical value =2
Hence margin of error =2(std error) = 1.2
Confidence interval 95%
Lower bound = Mean - margin of error = Mean -1.2
UPper bound = Mean +1.2
Hence , 95% of all of these values of x should lie within a distance of __1.2___ from μ .
